DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 537,408, dated April 9,1895.

Application filed May 3, 1894. Serial No. 509,906. (No model.)

To all whom it may concern:

Be it known that I, LEMUEL COBURN, a citizen of the United States ofAmerica, residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Doorflangers, of which the following is a specification.

This invention relates to constructions for sliding doors and trolleyhangers therefor which are designed as improvements on the contrivancesdescribed and shown in Letters Patent of the United States to Coburn andSumner, dated July 15, 1890, No. 432,225.

The invention consists in forms or construcr5 tions and combinations ofparts all substantially as will hereinafter fully appear and be setforth in the claims.

Reference is to be had to the accompanying drawings, in which- Figure lis a perspective viewshowing particularly the side of a freight car withthe trolley and connections between it and the car door. Fig. 2 is avertical section across the door, trolley, trolley connections andadjacent parts, the door being in its closed and flush position. Fig. 3is a similar view showing, however, the door as drawn outfrom its flushposition ready to be slid longitudinally away from the door opening.Fig. 4 is a perspective view on a larger scale showing the pendant forthe trolley, and the door fixture, or bushing, which is engaged thereby.Fig. 5 is a vertical cross sectional view of the said door fixture, orbushing. v 3 5 Similar characters of reference indicate correspondingparts in all of the views.

In the drawings, A represents the side wall of a freight car having thedoor opening, a, above which on the outer side of the car the 40 trolleytrack, B, is supported horizontally in the bracket, 1), 1).

C represents the door to fit closely within the jams, or casing, of thedoorway.

Said trolley track, B, as shown, consists of a tube which is ofagenerally rectangular cross section having the lower edges curved intowardthe median plane and then turned upward so that the bottom of thetube has a trough-way, as, at each side of the intermedi- 5o atelongitudinal slot, or opening, y. The said trolley track should,manifestly, be of a length equal to about twice the width of the door.Each trolley, of which two are provided, consists in part of a pair ofroller carriages, d, d, running in the trough-ways of the track, andalso of the pendant, f, which is constituted in substance by abarperforated through its upper portion to embrace the axle of the rollercarrier and having at the bottom the crossfoot which provides twoshoulders, f f to have a supporting, as well as a laterally sliding,engagement with the bushing, D, oneof which is provided in combinationwith each trolley and which will be now described as consisting of apeculiar hollow casting essentially comprising a front-plate, g, forattachment by screws, or otherwise, at the front of the car door, arearwardly extended hollow body, g with a horizontal top wall, g whichalso stands forwardly beyond the plane of the front plate and which topwall has the transverse slot, 9 of less width than the distance betweenthe extremities of the cross foot, f although its width is greater thanthe width of said foot. The car door is apertured atits 7 upper edge, asseen at 71, for the accommodation of the said hollow body so that whenthe face plate, 9, is fastened on the front of the door the slot, orway, g for the engaging cross-foot of the pendant will have its exten-8o sion both forward, and to the rear, of the front face of the door.See Sheet 2 of the drawings. The face plate, g, is apertured, as seen atg while the top wall, 9 is continuous across the front edge to form anend boundary 9 of the slot, 9

No provision is made, as will be apparent on inspection of Figs. 2 and3, for any considerable degree of lateral movement of the pendant,butthe relations of the pendant and 0 bushing, D, are such that, as thedoor is moved laterally, it, and its bushing, slide relatively to thecross-foot of the pendant, which cross foot is always in a supportingand sliding engagement with the opposite parallel 9 5 lips, bars, ribs,or flanges, as they may be variously regarded, at the top of the bushingor petticoat, and which in the particular design shown are constitutedby the inner margins of the said slot, 9

The lugs, 'i,j, 7', shown on the side of the car are desirable asdetermining the extent of outward movement necessary for the car-door tocarry it clear from the front face of the car, and to prevent excessiveoutward movement of the door, all preparatory to sliding it clear fromthe door-way.

The pendant is engaged with the bushing, D, by being turned quarter wayaround so that the cross-foot ranges along in line with the slot, gthrough the top wall so that the crossfoot may be carried below theunder side of said top whereupon the pendant is returned to its positionwith the foot across the slot.

Uusually in opening the door it is drawn forwardly at its bottom to itsoutward limit, as indicated by the dotted lines in Fig. 2. Its lower endsupport is now the fulcrum whereby to swing the door from its lower edgeso that it, as a whole, assumes the position free, outside of, andparallel with, the front of the car.

While the novel devices have been more particularly illustrated andreferred to as utilized for a freight car, they are, manifestly,available for barns, sheds, warehouses, and other structures; and whilethe pendant is shown as combined with a certain kind of roller-carrier,substantially such as is illustrated in the patent of Ooburn and Sumner,dated September 29, 1891, No. 460,501, which carrier in turn is shown asrun on a certain trolley track, the pendant may, without departing fromthis invention be carried by a different construction of roller carrier;while the roller carrier may have, provided therefor, some constructionof trolley track different from the one specifically shown.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with the car or other structure having the door-way,a trolley track above and outside of the plane of the doorway, rollercarriers to run along said track and the pendants supported by saidcarriage having the cross foot, of the door to fit within said way andhaving at its upper portions metallic bushings, each of whichessentially comprises a top walla portion of which stands outwardlybeyond the outer face of the door, and which has the transverse slot, gthereth rough,with the under boundaries of which the said cross foot ofthe pendant engages, substantially as and for the purposes set forth.

2. The combination with the car with a door-way, a trolley track aboveand outside of the plane of the door-way, roller-carriers and pendantshaving the cross foot,f ,f of the door provided at its upper edge withthe aperture, h, and having the bushings, D, D, each comprising theface-plate, g, rearwardly extended hollow body, 9 which is set withinsaid aperture, h, and provided with the top wall, 9 which forwardlyoverhangs the faceplate and which is provided with the slot, 9 under theside boundaries of which the opposite extensions of the foot havesliding engagements and which overhanging top wall has the portion, 9forming an outer end boundary for said slot, all substantially as described and for the purposes specified.
